Question

Solve for B A=7B+CB=

Answer 1

Given

`A=7B+C`

Solution

Step 1

Subtract C from both sides

`\begin{gathered} A-C=7B+C-C \\ A-C=7B \end{gathered}`

Step 2

Divide both sides by 7

`\begin{gathered} (A-C)/(7)=(7B)/(7) \\ \text{Simplify} \\ B=(A-C)/(7) \end{gathered}`

The final answer

`B=(A-C)/(7)`
